You were mistaken for a guy bc you had baggy clothes he told you to change in the boys locker room but you kept telling him you were a girl he just said that you wanted to check out girls

"You have to unless you want a bad grade."

You didn't wanna go in but you went into the locker room you rushed to a toilet so nobody could see you changing but they were locked because of the clogged toilets.

What do you do?
